Versatile Battery Compatibility

This tester checks AAA, AA, C, D and 9V cells plus common button types such as CR2025, CR2032, LR44 and CR123A. It also reads 1.2V rechargeable AA and AAA batteries. Home users and technicians can verify many household chemistries with one compact device.

Steady Magnetic Contact

A magnetic end holds each cell firmly in place during measurement, giving a more stable connection than friction-only testers. The LCD shows precise voltage and a clear Good, Weak or Poor indicator within three seconds, so sustained readings remain consistent without wobble.

Pocket-Sized Durable Build

The unit measures 3.77 by 1.29 by 1.18 inches and weighs 1.41 ounces, slipping easily into a drawer or tool bag. A rigid triangular slot and firm contacts prevent shifting while protecting battery casings. No external power is needed; the tested cell powers the tester itself.

Questions about this item

Does the DLYPOW tester generate heat or noise when checking batteries continuously?

The tester draws its power from the battery being tested, so it produces no fan noise and no measurable heat during extended use.

What extra equipment must I already own to start testing with this unit?

No additional equipment is needed; the device is powered entirely by the battery under test and requires no external supply or cables.

Will the tester give reliable readings on older 1.2 V rechargeable AA and AAA cells I still have?

Yes, it supports 1.2 V rechargeable AA and AAA batteries alongside standard 1.5 V and 3 V types, displaying voltage and a Good/Weak/Poor status for each.
